The University of Virginia says it’s creating a group to explore its policies and campus culture after a Rolling Stone article on an alleged gang rape prompted an “intense, ongoing period of introspection.”

Advocates for sexual-assault victims say Rolling Stone’s backpedaling from an explosive account of a gang rape at the University of Virginia doesn’t change the fact that rape is a problem on college campuses and must be confronted — even as some expressed concern that the magazine’s apology could discourage victims from coming forward.
